Joii'iv L. TAYLOR, or CHICAGO, ILLINOISQASSIGNOR To TAYLOR PoRTAELE sTEEL DERRICK COMPANY, A CORPORATION OF ILLINOIS.

To all whom it may concern: 3 Be it known that. 1, JOHN L. TAYLOR, a

Jcitiz en of the United States, residing at Chicago, in the county of Cook and State and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in platforms for attachment to gondola cars and adapted to. support der-.

ricks when loading and unloading a car.

The invention comprises various detalls of constructlon and combinations and arangements of parts which will be hereinafter fully described, shown in the accom panying drawings and then specifically de fined in the appended claims.

I illustrate my invention. in the accompanying drawings, in which Figure 1. is a side elevation showing the application of my platform to a gondola car. Fig. 2 is an enlarged detail sectional View through a part of the platform and the wall of the car to which it is fitted. Fig. 3 is a vertical sectional view through the platform and adjusting bracket, thetwo being disassembled. 7 view of a portionof the platform. Fig.- 5 is a detailperspective view of a clamping bracket member. Fig. 6 is a sectional View transversely and vertically through the platform and bracket member. 7 is a top plan View of the platform showing in 7 top plan the edge of the car to which it is fastened, and Fig. 8 is a side elevation of a portion of the wall of the car with the bracket attached thereto.

Reference now being had to the details of the drawings by letter, A designates the side wall of a gondola car having the usual truss rods B underneath the same.

C designates the derrick platform, made preferably of metal and having ribs D projccting from the under surface thereof, and upon which platform is the-hollowpost E of a derrick, the superstructure of which is cut away as it forms nopart of the present invention, and to the upper surface of Fig. 4 is a bottom plan" GoNnoLa DERRICK.

which platform brace bars are fastened and which are also broken away and which are adapted to brace said derrick post.

Pro ect1ons C, integral with the bracket members H, are adapted torest upon the upper edge of the side wall of the car and the under surfaces of said. projections are serrated as at L, while an upright face of the bracket H is designed to bear against the inner face of the car and the channel iron K against the outer face of the side wall of the car. Bracketmembers N are fastened to said beams K, by means of bolts 'N, and each is provided with ribs N upon its upper surface and whichare parallel to] each otherand". the upper surface of said members N intermediate the ribs and the edges of the bracket members are provided with series of serrations P which are adapted to engage the teeth -L formed upon the under surface of said forwardly pro .jecting portion C upon either sideof the slot C therein, as shown clearly in Fig. 4: of the drawings. A bolt 0 passes through the bracket member N, the head of said bolt engaging the under surface of said bracket member and the shank portion thereof be- ,ing adapted to pass through one of said slotsC and to receive a winged nut O.

Said ribs N upon the bracket member N;

are adapted to engage the spaces C intermediate the ribs C which are formed on the under surface of the platform. The

bracket members N and said extensions H upon the under surface of the platform serve tocotiperatewith each other to adjust and hold the platform upon the walls of different thicknesses of gondola cars, the

teeth uponthe bracket member intermeshing with the teeth upon the under surface 'of the platform, as will-be understood.

flanges thereon are sufliciently narrow so as to allow said irons to yield to compen-= sate for the adjustment of the bracketsto varying widths of walls of gondola cars upon which it may be desired to mount-the derrick, this adjustment being further made possible by having a loose joint between the lower ends of the braces Q and the channel irons K. r

A rod, designated by letter M, has a head M which is countersunken in a hole in the platform and its threaded portion engages.

a threaded aperture in the turn buckle M and also a winged nut M Said turn buckle carries a pin R to which one end of the chain R is fastened, the other end being adapted to engage over one of the truss rods B. Other rods, designated by letter R have their heads countersunken in the platform and are connected with the turn buckles R which in turn are connected through the medium of the chains R with one of said truss rods B. By the provision 'of the rods with chains attached thereto sition by the interlocking teeth upon said bracket member and the under surface of the platform by the turning of the winged nuts upon the bolts 0. The chains form means for holding the platform securely to the truss rods upon the truck of the car, as shown. 1

What I claim to be new is 1. A derrick platform for gondola cars comprising a platform having downwardly projecting bracket portions for engagement over the upper edge of the side wall of a car and a horizontally extending rib por tion serrated upon its under edge, channel i beams, braces connecting the lower portions of the latter with said platform, a bracket member fastened to each channel beam and 1 having serrations upon'the upper edge thereof adapted to grip serrations upon the under edges of the ribs up'onthe platform, and means for holding the serrations in interlocked relation, as set forth.

2. A derrick platform for gondola cars comprising a platform having downwardly projecting bracket portions with a forwardly extending reinforcing rib having I serrations upon the lower edge thereof,a channel beam adapted to cooperate with the bracket portion for engagement with the opposite walls of the side of a car, a brace connecting said channel beam and the outer portion of the platform, a bracket member having ribs projecting from the upper horizontal face thereof and designed for engaging grooves in the lower edges of the ribs underneath theplatform, and clamping means for holding the serrations upon the bracket member and ribs in locked relation with one another, as set forth.

3. A derrick platform for gondola cars comprising a platform having downwardly projecting bracket portions with a" forwardly extending reinforcing rib having an elonsurfa'ce thereof and a groove adjacent thereto, a channel'beam having brace connections between the same and the plat-' form, an adjustable bracket member with ribs upon the upper horizontal face thereof adapted to engage said grooves and having serrations ad acent to said ribs and designed to engage the serrations upon said forwardly extending part of the rib underneath the platform, clamping means for channel beam in adjusted positions, and stay gated slot and serrations upon the under holding the adjustable bracket member and chains and rods connected to the platform and adapted to .be fastened to a part of the car, as set forth;
